TROLLEY OR FEED WIRE ANCI-IOR FOR MINES.

Application filed May 2, 1923.

To ZZ whom, t 12mg/ concern.'

Be it known that I, Mormon J. Mirorrnme, citizen of the United States,residing at Dun Glen, in the county ot Jelterson and tltate of Ohio,have. invented certain new and useful linprovenients .in '.lrolley or'Feed lllire anchors ior Mines, oit which the tollowing is aspecification.

rThis invention relates to an improved .rolley or 'Feed Wire anchor Ytorniines and seeks, ainoi'ig other objects, to provide a siniple andcliicient device which may be readily embedded in the root' of a. n'iinefor anchoring the end ot' a trolley wire or the like. i

rThe invention seeks, as a further object, to provide a device 'whichWill be constructed to e'liiectually withstand the pulling strain ot.'the trolley ivire.

And the invention seeks. as a still turther object, to provide a devicewhich, when en'ibedded in the root or a mine, will be pri-'vented tronidropping down.

Other and incidental objects will appear' liereinailter.

.ln the drawings:

Figure i is a side elevation showing my improved anchor in use Figure 2is a Jront elevation ot the device. and

l*1 igure Si is a 'fragmentary side elevation showing a slightniodiiication of the invention..

ln carrying the invention into ellect, l employ a preterably cylindricalshank l() tapered toward its upper end and upset to detine a preferablydat 'forwardly overhanging spur ll. Near its lower end, the shank islfn'ovidi-d with an annular stop shoulder lil and, as will he observed.the spur ll lies "within the diameter ot the shank at the upper 'tace otsaid shoulder, Formed on the shanli: at its lower extremity is arearwardly directed head in the nature of a bool: lf3 proviilcd with ayslot or opening 141 entering through thi` 'Front tace oiE the head.Formed en the head in spaced relation to the shank is an innvardly andreari` ardly divergent bracing leg l5 lying in a plane with. the shanland provided ivitl a flat end tace in a plane with. the upper tace otthe shoulder l2.

ln use, a vertical bore is 'termed in the roof ot the naine toaccommodate the shank Serial No. 636,276.

l0 when, as suggested in Figure l of the drawings, the shank is insertedinto said bore until the stop shoulder l2 strikes the root. the head orhook 13 being, ot course, faced Way troni the direction ot pull ot thetrolley Wire or feed Wire to be anchored. llllicn the shoulder l2 isthus seated against the root ci the niine, the leg l5 will, as will beseen, be caused to coincidently engage the mine root' in the rear ot theshank for bracing and supporting the shank While the spar il at theupper end of the Shank Will sinh into the Wall of the bore in the mineroot 'tor securiniT the device in place. Thus, a trolley Wire or `feedWire may be engaged with the head or hook 13 to be anchored by thedevice and. it desired9 a turn buckle, as conventicnallyY illustrated indotted lines aty 1G, may be employed 'for' connecting the trolley Wireor feed Wire with the device? so that said turn buckle may be adjustedfor tensioning the Wire. As will be perceived, the leg l5 of the devicewill rigidly brace the shank` l0 against the rearward strain ol the Wireso that the device will thus brovide a secure and firm anchor' :for theWire.

ln Figure 3 of the drawings, l have illustrated a slight inoditicationof the invention which is' practically identical with the preifcrredembodiment with the exception that the shank o'f the device, indicatedat 10', is 'tornied at its lower end with a rearwardly directed head inthe nat-nre ot an eye i7, said head or eye carrying a rearwardly dirested leg i8 corresponding to the leg 15 and being provided with acentral opening i9.

Having thus described what is claimed as new is:

ln overhead anchor for mine trolley wires consisting of a shank to beinserted in a bore in the root of the mine and having a stop shoulderintermediate its ends to abut the root.J the shank above said shoulderdelining` a longitudinal spur adapted to enihed itself in the wall otthe bore.y a head at the lower end ot the shank having an openingtherethrough to be engaged by the trolley ivirc terminal. and a bracingleg rising troni the head in divergent relation to the shanlr andabutting` the rootI in the plane of the stop shoulder.

ln testimony whereof I ailiX my signature.
